ANTIBACTERIAL ACTIVITY TEST OF LAMELLODYSIDEA HERBACEA SPONGE EXTRACT FROM THE WATERS OF POOPOH VILLAGE, MINAHASA REGENCY

Infectious disease is one of the diseases that is currently became a health problem in the community. Along with the increase in cases of infection, there is also an increase in cases of resistance to antibiotics. The biodiversity of Indonesia exhibit a potential at anti-bacterial which could be develop to become antibioctics candidate. This study aims to determine the antibacterial activity of Lamellodysidea herbacea sponge obtained from the waters of Poopoh village, Minahasa Regency against the growth of Staphylococcus aureus and Pseudomonas aeruginosa bacteria. Extraction was carried by maceration out using 95% ethanol solvent. Anti-bacterial testing using agar diffusion method (Disc diffusion Kirby and Bauer). The results showed that the ethanol extracts of Lamellodysidea herbacea sponge had the largest inhibition zone on Staphylococcus aureus bacteria at a concentration of 250 μL/disc of 7.5 mm and Pseudomonas aeruginosa bacteria at a concentration of 250 μL/disc of 7.33 mm, both inhibition zones were in the medium category. Based on this study, it can be concluded that the largest inhibition zone is found in Staphylococcus aureus bacteria.
